An influential Twitter user must be highly active (e.g. able to start new discussions, have ideas that impact other users' behaviors, etc.). Additionally, the user's tweets must be credible, relevant and highly influential (i.e. liked and retweeted by a large number of other users). If the tweets of highly influential users are credible and the polarity of their tweet content is positive, they are highly acknowledged and recognised by the community. In short, for a Twitter user to be considered influential, we combine the efforts of [1]}, [2]}, [3]}, [4]} and calculate the influence score through Algorithm REF  line 7.
